Your merged PDF is ready
Merge complete. Your PDF has been downloaded.
How it works
- Add files in any order, then use the up/down arrows to arrange the order they'll appear in the final PDF.
- Merging happens locally using pdf-lib in this browser tab. BrowserPDF has no file-upload endpoint.
- Page counts shown per file are read directly from each PDF so you know what you're combining before you merge.
Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Files are combined in your browser's memory, so the practical ceiling is your device, not a quota on our side.
Can I change the file order before merging?
Yes. Drag rows into position, or use the arrow buttons; the merged PDF follows the order shown in the list.
Does merging reduce quality?
No. Pages are copied into the new document losslessly; nothing is re-rendered or recompressed.
